An adult child who has brought the client in to be evaluated has been told the client has Alzheimer's disease. The adult child asks the nurse if all the children of the client are going to get the disease
The nurse responds that which of the following is the greatest risk factor for the development of Alzheimer's disease? 1. Age
2. Genetic predisposition
3. History of previous head injury
4. Environmental exposure
1. Age
Rationale:
Growing older is the greatest risk factor for the development of Alzheimer's disease. The combination of genetic predisposition and environmental factors also affect the risk. Some genetic mutations on specific chromosomes have been shown to cause Alzheimer's disease but these genes account for less than 5% of all cases of Alzheimer's disease. Epidemiological studies have also shown some increased risk related to history of previous head injury.
